I've recently noticed a large portion of the fingerprint data falls into the "No Match" category, about 29% of all devices connected to the network.
It seems to be only Apple devices that are not being identified - I have determined this by looking at the hostnames of the devices. It's a mixture of iPads, iPhones, Macbook-Air. However there are devices of these same type that are being matched, so it's not as if all Apple devices are failing to be matched.
We're running NIOS 7.0.3, is anyone else seeing this behaviour?

If the Apple device has been updated to iOS9 you need to create a new DHCP Fingerprint since Apple has changed the DHCP Parameter Request List.
Create a new "iOS9" DHCP Fingerprint using the DHCP Option 55 parameters "1,121,3,6,15,119,252" and test it.
